' 3 Claims.

My invention refers to a scoop to be used to removing .fire ,ash remaining. in and around the retort oia .furnace after the clinkers have been removed from the fire pot by means of tongs.

being used. It is an important object of my invention to H provide a device of the character described having a relatively small number of parts easily assembled, and which will .not get out of order It,is a fu'rther object of my invention to {novice moved in and around the'retort of a furnace, and which may be pushed sideways through the fire box, or may as readily be used as a back-scoop.

It is a still further object of the invention to provide a device of the character described which is simple to manufacture, and which may be produced for sale cheaply.

Other objects and advantages of the invention will become apparent during the course of the following specification, and accompanying drawings, forming part of the specification, wherein like numerals are used to designate like parts throughout.

In the drawings:

Figure 1 is a perspective view of the embodiment of my invention, and,

Figure 2 is a transverse section through the scoop, taken substantially on the line 22 of Figure 1.

Referring now in detail to the drawings, the numeral 5 designates an open-end scoop formed from a single piece of galvanized metal having a substantially fiat but slightly laterally curved bottom 6, upstanding sides I slightly tapered adjacent the open end of the scoop, and an outwardly curved back section 8 therebetween, the said elements 6, 'l and 8 defining a receptacle into which ashes in the fire box of a stoker may be pushed or drawn by means of a longitudinal iron handle 9 bent as at ID to form a downwardly extending portion ll upon which the scoop is rotatably mounted by means of a narrow metal brace member, riveted to the sides, as at l3, to form an inverted U arranged between the ends of said scoop.

It should be noted that the intermediate section 14 of the U when mounted is not parallel .a. stoker scoop device which, becauseof a novel L, design and arrangement of the parts, may be to the plane of the bottom 6 but has one corner l5 upraised, .so that the extending portions, of the handlefi, when passed through a central opening It in saidintermediate section will 11am a plane angularly disposed relative to a perpendicular planefpassed through the axis ofthe, opening lithe purpose of which angular mountingwill later become apparent. The handle 9. is alsoprovided with a loop I! at'its free end as ahand rip when the, scoop isrbeing used, and the longitudinal portionof the handle, 9 betweenthebend Ill and the loop, ll is, disposed at an angleof ap- 'proxirnately 45 degrees to .the planeof the bottomfi. 15

pposed collar members IBand l9 are carried on the extending portion, H, on oppositev sides of intermediate portion l 4 of brace member I 2, the said collarmembers being provided ,with annular I flanges and 2|, respectively,' arranged to bear against the respective top and bottom of said portion l4. Collar member I8 is secured on the portion I l by means of a pin 22 which passes through said collar and said portion in registering openings therein. The collar l9 and its flange 2| is biased against the underside of the portion M by means of a helical compression spring 23 surrounding said extending portion H and disposed under compression between the underside of the flange 2| and an annular flange 24 formed on a collar 25 carried by the portion II and secured thereon by a pin 26 engaged in registering openings in the said collar and portion 1 I, respectively.

As disclosed, the scoop 5 is mounted for rotary motion about the extending portion H, and because of the applied energy of the spring 23, the scoop 5 will be held secured in any selected position relative to the handle 9 by means of the opposed flanges 20 and 2| impinging upon the respective top and bottom of the portion I4. The angular disposition of the extending portion ll provides a greater clearance when the scoop is used to clean ashes close to the furnace door and admits of greater maneuverability of the scoop when cleaning around the retort.

It is to be understood that changes may be made in the shape and arrangement of the parts within the scope of the sulojoined claims without departing from the spirit of the invention.

Having thus described my invention, I claim:

1. In a device of the character described, the combination of an open end scoop having a lat erally curved bottom, upwardly extending sides and an outwardl curved closed end connecting said sides, a brace member formed as an inverted U secured on said sides intermediate the ends and extending upwardly of said sides, the portion of said brace member intermediate said sides being tilted slightly relative to the bottom of said scoop and having a central opening therein, a longitudinal handle bent at an angle near one end thereof to form an extending portion terminating in a hand grip and a relatively short dependent portion adapted to engage in said central opening rotatably mounting said scoop thereon, a flanged collar secured on said dependent member, the flange thereof being arranged to bear on the sides of said brace member removed from said scoop. a second flanged collar slidably carried on said dependent member, the flange thereof bearing against the side 01' said brace member adjacent said scoop, the said flanges cooperating to engage the said brace member therebetween, a third flanged collar secured on said dependent member closely adjacent the end thereof, and a helical compression spring surrounding said dependent member and mounted under compression between the flanges of said second and third collars to press said second collar and flange against said brace member whereby said brace member is releasably secured between said first and second flanges to maintain said scoop in a predetermined position relative to said handle.

2. In a device of the character described, the combination of an open end scoop, a vertically disposed brace member provided with an opening therein secured to said scoop, a handle having a downwardly extending portion arranged in registry with said opening, a first collar abutting the upper face of said brace member and secured to said downwardly-extending portion, a second collar arranged below the lower surface of said brace member and mounted for slidable movement on said extending portion toward and away from the brace member, an annular flange carried by the lower end of said extending portion, and resilient means interposed between said flange and said second collar and connected thereto for biasing said second collar toward said brace member.

3. In a. device of the character described, the combination of an open end scoop, a vertically disposed brace member provided with an opening therein secured to said scoop, a handle having a downwardly extending portion arranged in registry with said opening, a first collar abutting the upper face of said brace member and secured to said downwardly extending portion, a second collar arranged below the lower face of said brace member and mounted for slidable movement on said extending portion toward and away from the brace member, an annular flange carried by the lower end of said extending portion, and resilient means embodying a compression spring circumposed on said extending portion and interposed between said flange and said second collar for biasing the latter toward said brace mem ber.
